Abstract
An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may communicate with a wireless base station using a 5G New Radio (NR) communications protocol. The wireless circuitry may include a phased antenna array. The electronic device may perform antenna scaling operations in which the active antennas in the phased antenna array change over time to optimize wireless performance and power consumption. The electronic device may inform the base station when antenna scaling operations have occurred. This may allow the base station to compensate for power density discontinuities associated with the antenna scaling operations. If desired, the base station may break transmit and receive signal beam correspondence and the electronic device may use different antenna scaling settings for transmitting and receiving signals.
